Which figure represents the electric field lines of two positive point charges? a. figure ab. figure bc. figure cd. figure d

Electric field lines of positive charges are always radially outwards

So here all field lines must have tendency to move out radially as well as two field lines never intersects with each other

So here field lines also do not intersects with each other

So overall the figure C is perfectly representing the field lines of two positive charges as these lines are not intersecting and also originating from two positive charges.

So answer must be

FIGURE C

d) physical means can be used to separate the components of air.

i think its c if i'm wrong
